HK1 MAX PLUS TV Box Features Upgraded Rockchip RK3368PRO SoC with USB 3.0, HDR Support

Rockchip RK3368 octa-core Cortex-A53 processor @ 1.2 GHz was introduced in 2015 mostly in TV boxes running Android 5.1 such as Beelink i68 or Tronsmart Orion R68.

Unsurprisingly we don’t read much about new Rockchip RK3368 products four years later. But Rockchip appears to have launched a RK3368 “refresh” with RK3368PRO processor equipped with most of the same features, plus the addition of a USB 3.0 interface, and HDR support. The company also updated software support to Android 9.0 Pie.

I’ll let you find out what a “brush button” is since I have no idea. It just looks like a typical 3.5mm AV port with composite video and stereo audio, but the specs specifically indicate there’s no such AV port. Sometimes they include the recovery button in such opening, so maybe that’s the case here.

The box runs Android 9.0, and ships with an IR Remote control, a power supply, an HDMI cable, and a user manual by default. There are also optional accessories such as T1 voice remote for Google Assistant, and that happens to have shortcuts for Netflix, YouTube, and Google Play as shown below.

Price starts at $42.69 including shipping for the model with 4GB RAM, and 32GB flash, but the 64GB version is not much more at $45.73. T1 voice remote adds about $9 to the total price.

GPU = PowerVR? Skip.


Since Amlogic made the S912 to compete against the original rk3368, maybe just maybe Amlogic will re-release the S912 with Pie. One can always dream. Still have S912 devices that run exceptionally well on CoreELEC software, but it would be nice to update the Android OS.


If it can sustain 1.5 GHz on all 8 cores, it could directly compete with the NanoPi Fire3 for CPU intensive tasks, especially with 4 GB of RAM.


The original couldn’t*, I doubt this one will. Let’s wait and see, though.

* Not only that, but it throttled the “big” cluster to 1.2GHz** whenever the “small” cluster reached 1.1GHz**

** Figures by memory, might be off by some hundred of MHz.


In the listing it is shown that the memory is DDR3 and not DDR4. The original RK3368 paper also supports this. It is plausible that DDR4 support was added considering the modern S905X2/X3 uses that, but for now, it appears to have 4 GB DDR3.


I bought this box recently. I am suffering a big problem… It not recognize external drive before formatting it.
